FLOAT.

To all whom it may concern:

Be it known that I, JAMES B. HILL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Floats, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Hy invention relates to floats and is of particular service in the formation of those floats which are employed for supporting fish nets, and the invention has for one of its objects an improved construction of floats that will enable the same to withstand heavy deep sea pressures.

My invention has fo-r another of its objects an improved construction of floats that will enable the same readily to be attached to the fish nets or other device which is to be buoyed.

I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which- Figure 1 is a view in elevation of a float ,as I preferably construct the same; Fig. 2

is a longitudinal sectional view of the float; and Fig. 3 is an end view of the float.

Like parts are indicated by similar characters of reference throughout the different figures.

The float proper is in the form of a hollow closed ended tube l which is water tight. 'The tube is drawn out of a sheet of suitable metal such as aluminum, one end of the tube being closed in this drawing process while the other end of the tube is initially open. Before this latter end of the tube is closed the outsetting annular beads 2 are rolled in the tube whereafter the tube end that was open is spun completely closed so that the tube is water tight.

I am aware that it is old to roll beads in the tubular portions of fishnet floats, but these beads were insetting, the depths of the beads thus being materially limited owing to the crowding or upsetting of the metal upon the interior of the tube and fur ther owing to the limitation of the size of the mandrel employed in the beading process. As a consequence the efforts of the prior art were limited to the resistance they afforded to the collapsing action of deep sea pressure. Insetting beads of the prior art,

moreover, furnished no protection against injury of the unbeaded portions of the tube so that these unbeaded portions were liable to be dented and were therefore more subject to the depressing or collapsing action d ue to deep sea pressure. Owing to the limited added strength furnished by the insetting beads it has been the practice to supplement the same by supporting diaphragms or Ydisks within the floats, these disks being located between closely approached insetting beads. In accordance with my invention the beads are outsetting so that the depths thereof may be suited to the pressure that the float should withstand, while at the same time thezones of the float between the beads are guarded, by the beads, against injurious contact with objects so that these tube or float Zones may remain perfectly cylindrical and may therefore be unpredisposed to the collapsing action of deep sea pressure.

I provide a ready means for attaching the float in place in the form of caps 3 upon the ends thereof, the rims of these caps being so tightly spun or crimped upon the float ends as to be permanently or irremovably fixed in position so as to provide assurance against the separation of the float from its cap ends and so as to make the cap ends relatively fixed whereby the cords are attached to the float at relatively fixed points. Each capI is provided with eyes t that are preferably margined by eyelets 5, these eyelets affording rounded edges for the eyes so that the float attaching cord or cords 6 will have minimum wearing' engagement with the float ends. The eyes 4 in each cap are desirably evenly spaced upon opposite sides of the float axis and all of the eyes of the float caps taken together are desirably in the same plane, this relative disposition of the eyes being maintained owing to the fixed relation of the caps and the tube.

Having thus described my invention, I claim as new and desire to secure by Letters Patent the following l. A'fishing float in the form of a hollow water tight cylindrical tube whose cylindrical wall is shaped to form a plurality of spaced apart outsetting annular beads as integral parts of the cylindrical wall of the float, the float having unbeaded cylindrical zones intervening between the beads and which are protected by the outsetting beads from injurious contact.

IGO

2. A fishing float in the form of a hollow water tight tube and having cord attaching caps Xedly secured to its ends whereby the places of securement of the attaching cord or cords are relatively fixed with respect to each other and with respect to the float proper, each of said caps having eyes therein through which cord portions may be passed between the caps and the tube ends,

l0 the eyes of each cap being substantially equally spaced upon opposite sides of the oat aXis.

In Witness whereof, I hereunto subscribe my name this sixteenth day of January A. D., 1912.
